Most of the vinyl monomers undergo radical polymerization. Hence all the monomers in the list will undergo radical polymerization. In the cationic polymerization, the intermediate is cation and hence the monomores which give more stable cation will lead to the cationic polymerization.
Thus the most stable cation will be formed in case of styrene from the given list. So the answer is option II.
